My lifting and turning, apparatusv has been illustrated 8.8111560]. for turning a boat though the same can be used in conjunction with any other bulky object" which it becomes. desirable to. lift and. turn..

In: Figs. 1,.2 and13; a boat It); hasabeenshown. having. a bow H: and-a stem l2; 'Ihesaidiboa-t 2 isalso provided with akeel l3 which extends throughout the length of the samefrom the-stern- I-2 to-the bow I'l. Inasmuch as the boat illustrated does not form any particular feature of the invention, the same has not beenshown in detail and the same will not be further described. The invention proper includes a support [4 on numeral 18;

The frame IT comprises twolongitudinal frame members 2! and 2 2' which are connected together at their outer ends by means of a transverse frame member 23. The said longitudinal frame members are further connected together at their inner ends by means of a transverse frame member 24; The frame [1- is soarranged' that the frame member 2-4" projectsabovethe water level 2.5. This frame-member is rounded at the upper portion of the same and forms a rest upon which the b ow ll of the boat may be placed. The frame IT is held partly submerged under the water in the manner shown in Fig. 1 by means of stakes 26 which are driven into the bottom- F8 of the lakeand to which the longitudinal frame members- Il may be bolted or otherwise secured.

The-supportl4 consists of two uprights I 5 and l '6' which extend upwardly from the transverse frame member 23 of frame- H. These uprights are connected together at their upper ends by meansof a cross frame member 21 and the said uprights arerigidly attached to the frame ll by meansofbraces 2'8 and 29. A base 30' is secured to the lower end. of each upright l 5- and lb. The variousparts of the frame H5 and the. support l4 may be bolted. nailed or otherwise secured to.- gether. The apparatus of my invention is. installed adjacent a dock which. Iihave. designated by the reference numeral 3'1? in the drawings.

This dock may. be of any suitable construction and; forming. no. feature of the invention, will. not

be: described in detail;

The. invention proper consists of an elongated drum 32: which. extends between: the two uprights t5. and I16... Thisdrumhas'twostubshafts 33 and.

yond th upright I 5. and by'meansof which. the. user stationed on the dock 3| may rotate the said drum. A latch 36 pivoted to the upright 15 is movable into the path of movement of the crank 35. When positioned as shown in Fig. 2, this latch restrains rotation of the crank 35 and drum 32 and holds the object to be lifted in elevated position as will hereinafter more fully appear.

Operating in conjunction with the drum 32 is a rope 31. This rope has an intermediate portion 38 which is disposed about the stern l2 of the boat It] and which is secured to the boat at the upper right hand portion of the same as viewed in Figs. 2 and 3 by means of a cleat 39. The end portions 4| and 42 of this rope are secured to the drum 32 at spaced localities substantially disposed apart a distance equal to the width of the stern I2 of the boat l0. This may be accomplished by running the ends of the rope through holes 50 in the drum andknotting the same as indicated at 56. Any other method may however be used for securing the rope ends to the drum. The rope is of suitable length so that when the boat is in the water, the intermediate portion 38 may be slipped under the stern of the boat to properly support the boat.

In lifting the boat, it becomes necessary to move the latch 36 out of engagement with the crank 35 and to then turn said crank. This causes both the end portions 4i and 42 to wind up on the drum 32. In Fig. 2, I have shown the rope 31 as partly wound up and the boat H) in elevated position. By moving the latch 36 into engagement with the crank 35, the boat remains suspended in the desired position.

For turning the boat over, I employ a catch best shown in Figs. 4 to 7 inclusive which has been indicated in its entirety by the reference numeral 43. This catch has been illustrated as constructed from a rod or stiff wire and includes a portion 44 which extends through a hole I45 formed in the drum 32 and which serves as a pintle for mounting the said catch for swinging movement. A portion 45 of the pintle 44 projects outwardly beyond the drum 32 and forms a bitt about which a portion of the rope 3'! may be wound. Issuing outwardly from the bitt 45 is an arm 46 which extendsin a circumferential direction about the drum 32 and which forms a leader for leading the rope about the bitt 45. The catch 43 may be swung from the position shown in Figs. 2 and 4 in which the same is clear of the portion 42 of rope 31 and to a position such as shown in Figs. 3, 6 and 7 in which the said leader is in leading position. The leader 46 is held in this position by means of a portion 41 which extends outwardly from the pintle 44 at the end opposite the arm 46 and which forms an ear or lug projecting outwardly therefrom. This ear is adapted to engage a stop 48 issuing outwardly from the drum 32.

The manner of using the invention is as follows: The boat while afloat is first moved between the uprights l and I6 and the bow ll of the boat run up over the rest 24. Inasmuch as the stern of the boat is supported by the water, this is easily accomplished manually. The rope 3! is next unwound sufliciently from the drum 32 to permit of inserting the same beneath and about the stern l2 of the boat. The part of the rope adjacent the cleat 39 is then wrapped around the cleat to secure the same thereto at such locality. The latch 36 is now disengaged from crank 35 and the said crank rotated. This causes the end portions 4| and 42 to simultane ously wind about the drum 33 thereby lifting the stern of the boat out of the water. In Figs. 1 and 2, the boat has been shown as completely lifted out of the water and at substantially an even keel. The winding of the rope continues until the reach 49 of the rope leading from the end portion 42 thereof lies adjacent the stop 48. Catch 43 is then swung over into the position shown in Figs. 6 and '7 in which the arm 46 crosses the said reach. If now the drum 32 is rotated in the opposite direction through crank 35, the reach 49 will slide along the arm or leader 46. This will cause the rope to be directed about the bitt 45 and the same will then occupy the position shown in Fig. 7. Continued turning of the crank '35 in the reverse direction will cause the portion 5| of the rope to continue to wind upon the drum 32. In this case, however, the rope now winds in the opposite direction from which it was formerly wound. As this portion of the rope winds up, the portion 4: unwinds. This causes the stern of the boat to turn as shown in Fig. 3. It will readily be comprehended of course that enough rope be wound on the drum in advance of operating catch 43 to turn the boat the desired amount. During turning of the boat, the bow Ii pivots on the rest 24 and is correspondingly turned. If the boat at the bow approaches too close to the end of the rest 24, the bow of the boat may be readily moved over manually to a position intermediate the end of the rest. Once the catch 43 has been moved into leading position as shown in Fig. '7, the weight on the ends of the rope is balanced, the weight on one side tending to wind up the rope and the weight on the other side tending to unwind it. When the parts are so disposed, the latch 36 is not needed and the boat will remain in any adjusted angular position. In launching the boat, the procedure is exactly the reverse of that just described.

While I have shown but a single lifting and turning device, it can readily be comprehended that two such devices may be used, one at each end of the boat. In such case, appropriate transmission mechanism will be employed for causing both drums to rotate simultaneously. Such mechanism being well known, will not be described or shown in this application.

The advantages of my invention are manifest. The boat can be readily moved from the water and elevated to a position above the surface thereof. With my invention,'the boat can be, after elevation, turned so that the same be partly or completely inverted. This permits of readily drying out of the boat during storage or of washing or cleaning the interior of the boat. At the same time, the boat is advantageously supported in any position, permitting'painting or repair of the same. With my invention, the boat can be raised out of the water and manipulated by a single operator, thereby permitting of' handling large boats by one person. The invention is exceedingly simple in construction and can be produced at a nominal expense. I

Changes in 'the specific form of my invention, as herein described, may be made within the scope of what is claimed without departing from the spirit of my invention.
